If possible, adjust the pump to start at 50% full rather than 10-20%.

better take into account the weight of water.
80 gallons would be something like 650#

if his attic was made with trusses he probably wouldn't
want that weight on them. I wouldn't.

Our "attic" is just a small 6'x24' room above our guest bath and laundry.
It's below the insulation so it doesn't freeze in winter or cook in the
summer. It has it's own 2x6 floor joists @ 16" OC that span about six feet.
Weight wouldn't be much of issue. But, it's only about 4 feet high and the
access hole is fairly small. I would probably have to install several
smaller tanks instead of one larger one.

In any case, that's kind of a last resort option as it would involve
running new pipes up to the attic. By the time I bought the tanks,
modified the plumbing, and installed and plumbed drip pans in case a tank
leaks, it's more trouble than it's worth.

Just one of those crazy ideas I was tossing around.
